I agree, different creatures and not a good comparison. All my centuries have been done under 5 hrs., but with a group. Some can do them under 4 hrs, not me. Obviously at major effort. You could walk/jog 24 miles with little effort. Yes, very different and depends on your goals and effort. I think this is why the term marathon isn't often used in cycling.
